BAR-BELL.

SPECIFICATION forming part Of Letters Patent No. 702,356, dated June 10, 1902. Application filed January 2, 1902. Serial No. 85,183. (No model.)

zen of the United States, residing in the city- .and county of Philadelphia, State of Pennsylvania, have invented a new and useful Im- 'provement in Bar-Bells, of which the following is a specification.

My invention consists of a bar-bell which is adapted for exercising after the order of a IO dumb-bell, the same being provided with novel means for adjusting the weight thereof by the useof a mass of pellets, particles, or small pieces of weighting material,preferably shot, which may be poured into and out of IS the closing and tightening member of the weight-receiving chamber without requiring removal of said member, while the weightreceiving capacity of said chamber may be readily adjusted by proper motion of said member. i

It also consists of novel details of construction, all as will be hereinafter set forth, and pointed out in the claims. I

Figure 1 represents a side elevation of a :2 5 bar-bell embodying my invention, a portion of the same being in section. Fig. 2 represents an end View thereof. Fig. 3 represents a section of a portion on line a; m, Fig. 2.

Similar letters of reference indicate corre- 5o sponding parts in the figures.

Referring to the drawings, A designates a bar-bell, the same consisting of the hollow heads or chambers B, to the base of each of which is secured the plate 0, which by means of the stud D connects the head with the handle E of the device.

F designates a longitudinally-extending screw-rod, which projects from the center of the plate Candis firmly connected therei 0 with, and G designates a follower which is fitted on said rod and provided with the thumb-nut H, whereby said follower may be screwed inor out on said rod F, so as to decrease or increase the chamber K of thehead and close the same.

chamber K and removed therefrom after the manner of pouring in order to adjust the weight of the head, said opening having a closure, such as the screw-plug L, whereby loss of the shot from the head through said opening is prevented,and means are provided for access to the chamber K through said follower. I

It is evident that both heads are similarly equipped with a follower, inlet, &c., so that they may be uniformly adjusted in weight.

The operation is as follows: The plug L is removed and shot poured through the inlet J until the chamber K is supplied to the desired weight, the follower having been moved in or out relatively to the weight said chamber is to occupy. When this is accomplished, the openingJ is closed and the follower moved in or toward the shot and clamped tightly thereagainst, forminga mass which is compact and will not shift, shake, or rattle. The bell may now be used for purposes of ,exer-. cising and the weight of the heads further changed or adjusted, as desired.

It will be seen that the weight in the chamher K may be increased by fractions of a pennyweight or by several pounds,'and this may be done so gradually as to be almostimperceptible to the user, avoiding the possibility of any strain due to abrupt increasein the weight, it being also evident that the weight may be similarly reduced, all at the command of the user of the article.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is?

l. A bar-bell having ahollow head, a mass of loose weighting-pieces therein, a follower adapted to adjust the weight-receiving capacity of the chamber in said head and tighten said pieces, said follower being provided with an opening affording access to said chamber without displacement of the follower and a closure for said opening.

2. A bar-bell having a hollow head, a mass of loose pellet-weights therein, a follower therein adapted to be moved in and out to adjust the weight-receiving capacity of the chamber in said head, said follower being provided with an opening adapted to form a mo communication with said chamber from the for connecting said head with the handle of exterior of the head, and a closure for said. the device and a removable closure for said 10 opening. opening.

3. In a bar-bell, a hollow head, a screw ris- 5 ing from the base thereof, a follower in said head mounted on said screw, said follower be- \Vitnesses:

ing provided with an opening, means for con- JOHN A. WIEDERSHEIM,

necting said screw with said head, means WM. OANER WIEDERSHEIM.
